The crystal structure of the title compound has been determined by the symbolic addition method from 934 observed three-dimensional photographic data. Crystals are monoclinic with a=8.14, b=8.86, c=9.32 Å (all ± 0.02 Å), and β=116.5°(2), Z=4, space group P21/c. The structure was refined by full-matrix least-squares method to R 0.091. The structure is stabilised by N-H … O and O-H…O type hydrogen bonds. The dimensions of the amide group, which is significantly non-planar, are compared with those found in other peptides.
